ZGMn13 (high manganese steel) lining is a suitable choice. The lining is reasonable in thickness and wearable. The surface hardness can reach HV500, which is equivalent to about HRC45. This can increase the wear resistance of the liner and increase the effective volume of the cylinder, thereby improving the working efficiency of the ball mill.
